Description of key information

In an OECD 305 study conducted under GLP conditions, Molyvan 855 does not exhibit a bioconcentration potential, as all measured components of the complex reaction mixture have bioconcentration factors (BCF) of less than or equal to 617, for both the low and high exposure levels.

Key value for chemical safety assessment

BCF (aquatic species):
617 dimensionless

Additional information

Key study

In an OECD 305 study conducted under GLP conditions, Molyvan 855 does not exhibit a bioconcentration potential, as all measured components of the complex reaction mixture have bioconcentration factors (BCF) of less than or equal to 617, for both the low and high exposure levels. Five main components (identified as A, B, C, D and E) were analysed and evaluated for bioconcentration potential, all of which had BCF values below 100. Component C was detected in some fish at the high exposure level on Days 28 through 60, but was not detected in fish from the low exposure level throughout the exposure period. Since results for all but one main component were below the limit of detection, the variation in bioconcentration factors could not be assessed, and the steady state attainment could not be determined. Four additional components (identified as F, G, H and I) were analytically monitored and resulted in BCFs ranging from 9 to 617.
